This was surprisingly decent. I don't usually play hand drawn/2D art games. I understand this is just a demo, so perhaps things will change upon release. The voice acting was a nice touch. As for suggestions, I have a couple.
1.) Robin could have a variety of outfits to wear. Or even something like pajamas at night.
2.) The story is unique, and I like the fact that the MC isn't a prick. Perhaps in the full game, you could add some animation to certain scenarios.
I won't bog this post down with a laundry list or anything. I simply wanted to share My thoughts. I'll have My eye out for this game. Good Luck.
